摘要

•Magnetocaloric effect (MCE) was studied in (Ce0.71Pr0.07Nd0.22)2Fe17-xAlx alloys.•All the samples adopt the Th2Zn17-type rhombohedral crystal structure.•The effective working temperature and RCP was greater than 40 K and 60 Jkg−1, respectively.•Low field large adiabatic temperature change of 5.6 K was realized at H = 1 T.•The performance-cost ratio is larger than some potential magnetic refrigerants.
